Brad is swimming in the ocean on a hot sunny day. he finds the water to be much colder than the sand on the beach, even though the sun is warming them both identify the reasons for brad's observation.
the water is colder than the sand because it requires more (energy/density/solvent) to change temperature. this is because the water had a higher (salt concentration/specific heat/evaporation rate) than the sand.

pick one of the ones in the parentheses for each one

energy & heat?evaporation rate

When Brad was swimming in the ocean and then he observed that the sand was more hotter than the water of the ocean.

The water is colder than the sand because the water needs more energy as compared to sand to change its temperature.

This is because the water has a higher specific heat than sand. This makes the sand cool and warm faster than water.

i do not know and i have a 100 in this class
